You can have a period without Ovulating, especially if your cycles are longer than the traditional 28-32 day range.
My other suggestion would be your thermometer. If I am looking at it right, it looks like you might be using a regular therm. that only measures to .1's. The BBT measure to .01's, which sometimes can make a big difference.
I understand your frustration, but if you can keep charting and figure out your cycles so you fully understand your cycle when you guys are ready to TTC again, I think it will help you get your BFP quicker!
